Specification of Letters Patent. Patented Aug. 21, 1917.

f Application led February 19, 1917. Serial No. 149,612.

fication containing a full, clear, and exact descriptiomfreference being had to the accompanying drawings, forming a part hereof.

- My present invention relates to certain improvements upon the hernial truss which is shown and described in my United States Letters-Patent No. 1,158,383, dated October 26, 1915, and the object of my present invention is to provide improved means for attaching the pad as well as the back disk to the bowed truss-wire or spring, in such a manner that the 'said -pad will more perfectly t the rupture and support the same automatically during the various movements of the body, whereby the truss will be more comfortable and eiicient during use.

A further object of my invention is to provide a surgical truss in which novel means for supporting and adjusting the pad are made use of, together with a novel arrangement of a torsional retaining-'spring adapted to be tensioned as delicately as desired, and which is designed to act upon the pad-support, after the-latter has been adjusted, to automatically maintain the pad yieldingly yet comfortably in contact with the rupture. v

A further object of my invention is to provide an improvedy and automatically adjustable back-disk which is connected with the supporting wire` or spring by novel and efficient means which will allow of its adjustment to t lean and stout persons vwith the same supporting wire, and to automatically maintain its pivotal connection with said wire during all thel various movements of the body of the wearer.

The invention consists in the novel combination .and arrangement of the various parts as hereinafter described and particularly pointedv out in the claims found at the end of this specification.

In the drawings:

Figure 1 is a top plan view of my improved truss.

Fig. 2 is an enlarged front elevation, partly in section, of the end `of the supporting-wire carrying the hernial pad.

Fig. 3 is a similar View of the opposite end of the supporting-wire, carrying the back disk.

Fig. 4 is a transverse section on the line 4 4 of Fig. 2, and

Fig. 5 is a transverse section through the back disk and connecting parts, and

Fig. G is a detail section, taken on the line G-G of Fig. 4.

The numeral 1 designates the bowed supporting-wire or spring of the truss, which is (in the present instance) formed with j an integral hook 2 at one of its ends and with another hook 3v at its opposite end detachably secured in kplace by having its internally-threaded tubular body engaging the threaded end of the said wire.

The usual sheath 4 of rubber, or other suitable material, is provided for said supporting-wire, for an obvious purpose.

A collar 5 is fixed upon saidbowed wire 1, by means of a set-screw 6, at a point adjacent the said hook. 3, and said collar carries a stop-pin 7 which projects from the inner face of said collar in a direction parallel with the adjacent part of the said bowed wire, and engages the end-walls of a curvedslot or recess 8, to limit the rotary movement of a ball 9 which `is loosely mounted on said wire, to rock a limited distance, and to slide axially thereon.

Said ball 9 has a fiat face which is normally in contact with the flat face of the said collar 5 which carries said stop-pin 7 ,p

and the said curved slot 8 is formed in the said flat face of said ball.

The outer surface of the said ball 9 is, of course, spherical in form, so that the socket 10 and the base-plate 11 of the hernial pad l2, may be adjusted to any angle desired, theV said base-plate being held on said ball by a U-shaped loop 13 havingfa ball socket 14 located diametrically-opposite the socket 10 of said base-plate.

One end of said loop 13 is hingedly connected to said base-plate and is readily detachable'therefrom' by having said end bent outwardly ata right-angle and the bent portion loosely engaging in a slot 15 formed in said base-plate, the other end of said loopbeing adjustably connected to said base-plate by means ofl an adjusting and clamping screw 16 passing loosely through a perforation formed in said end and engaging the threads of an aperture in the base-plate.

Thev apertured end of the said loop 13 is bowed supporting-Wire; two collars fixed on said wire at a distance from each other, the collar nearest the end of said wire having a stop-pin fixed in it and projecting therefrom in a direction toward the other fixed collar; a ball mounted on said wire torock and slide adjacent said fixed collar which carries said stop-pin7 said ball having formed in it a curved recess the opposite walls of which are engaged by said pin to limit the rocking movement ci' said ball; a tnbuiar shank on said bail; a sleeve mount ed on said tubular shank, to slide and to rock thereon; .means for closing one end of said sleeve; a spiral-spring having its ends fixed the one to said bali and the other to the means which closes the end of said sleeve,
